One factor in Leonard's decision could be the potential retirement of Popovich. A Thursday report from Wojnarowski stated that that people in the coach's "orbit" told him that next season could be Popovich's last as an NBA head coach (he's still set to coach the United States at the 2020 Olympics in Buenos Aires, Argentina).

Leonard has reportedly had an increasingly fractured relationship with Popovich and the organization throughout the course of this past season.
